A TTOR/VE ARTHUR E. LYBOLT, OF KANSAS CITY, MISSOURI.

SHADE-ROLLEB.

Application filed March 19, 1917.

[b all whom it may concern:

Be it known that I, ARTHUR E. LYBOLT, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Ii-flissouri, have invented certain new and useful Improvements in Shade-Rollers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to shade rollers and more particularly to rollers of this character adapted for vertical adjustment within a window frame, the principal object of the invention being to provide means for raising or lowering the roller, and clutch mechanism for retaining the roller and shade at an adjusted position within the frame.

In accomplishing this object I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Figure I is a perspective view of a window frame showing my invention applied thereto.

Fig. 11 is an end view of a roller illustrating the roller and curtain clutches and their releasing means.

Fig. 111 is a view of the roller, shown partly in section, illustrating the mounting of the guide clutches.

Fig. IV is a detail perspective view of the roller clutch and its releasing lever.

Referring more in detail to the drawings:

1 designates a window frame of the ordinary construction, comprising the opposite side ambs 22, a sill 3, and head jamb wherein the window sashes 5 are contained. Mounted at opposite sides or the window on the jambs 2 2 are guide strips 66, each of which comprises a flat, vertically disposed metal strip having inturned legs 7 at its opposite ends which are attached to the frame to space the strips therefrom, and mounted horizontally between said guides is a roller 8 whereon a curtain or shade 9 is wound.

.The means employed for supporting the roller between the uide strips 66', consists oi clutch members 10 and 11 that are located at opposite ends of the roller. The member 10 comprises a shank 12 that slidably and revolubly contained in a socket 13 atthe Specification of Letters Patent.

end of the roller and has a head 1-1: provided with an oblong aperture 15 for slidably receivingthe guide 6, the clutch member 11 is similar in construction to the member 10 and comprises a head 16 having an oblong slot 17, therein, for receiving the guide 6 and a shank 18 that is revolubly mounted in a cap barrel 19 that extends coaxial within a bore 20 in the roller, wherein a coil spring 21 is located, the spring being attached at its inner end to the roller and at its opposite end to the shank 18 in such a manner that the winding tension or the spring will tend to revolve the roller in one direction and the shank in the opposite direction so that the head 16 will eflect a grip on the guide 6 to retain the roller at an adjusted position.

To effect the clutch, the apertures 15 and 17 are made slightly longer than the width of the guide strips, so that the clutch heads, when held horizontally, will be free to more vertically on the guides but when slightly inclined will grip the edges of the guides to lock the roller thereto.

As the usual pawl and ratchet mechanism,

are eliminated in my construction, the means for retaining the curtain at an adjusted position, and for preventing its winding on the roller, comprises clutch members 2020 which are mounted in opposite ends of a cross bar 21 that is inserted in a hem pocket at the free end of the curtain; the said clutches comprising shanks 22 that are fixed in the bar and have apertured heads 23 similar to the clutch head 16 which slidabl receives the guides 6-G and are so p aced relative to the direction of tension of the curtain that the heads will be moved to effect a grip on the guides to prevent the curtain from winding on the roller.

To release the curtain to permit its being wound or unwound from the roller, I provide a cord 25, of such length that it may be reached when the curtain is at its highest position and which is attached to the upper edge of the cross bar 21 so that pulling downwardly thereon, will tilt the bar suiiiciently to release the clutch members 2020 from the guides so that the curtain may wind on the roller or be drawn therefrom.

In order that the curtain roller may be released from and moved vertically between the guides, I provide the clutch head 16 with a releasing lever 27, which is attached to the shank 18 and extends rearwardly therefrom in an upwardly inclined position, and attached to the lever is a cord 28, which ex tends over pulleys 29 and 30, mounted on the jamb head i at opposite sides of the frame and then downwardly to an accessible point at the lower part of the frame where it may be attached to a hook or latch 31 to hold the roller in an adjusted position. Also attached to the shank of the clutch member 10 to support that end of the roller is a cord 28 which extends up vardly and over the pulley 30, then downwardly along the cord28 to a point where it is attached thereto.

It will be seen that by attaching the cord 28 to the lever 27, by pulling on the cord will rock the lever upwardly to revolve the head 16 and release its grip on the guide strips 6, so that the roller may then be moved upwardly or lowered between the guides.

Assuming that the parts are so constructed, and the roller mounted on the end members 10 and 11 which in turn are slidably mounted on the guide strips 6-6 at opposite sides of the frame 1, if it is desired to raise or lower the curtain, the operator first pulls downwardly on the cord 25, thereby tilting the bar 21, so that the clutch members are released from the guide strips and the curtain is left free to wind on or from the roller. ll hen the curtain has been adjusted to a desired position the cord is released and the tension. on the curtain again e'fects the grip of the clutch members to hold the curtain at the adjusted position.

If it is desired to raise or lower the roller between the guide strips the operator releases the cords from the hook and draws downwardly on the cord 28, which rocks the lever 27 and moves the head 16 to release the grip on the guide (3. After being thus released, the roller is moved upwardly or downwardly by drawin in or paying out the cords 28-287 and may be locked in any adjusted position by releasing the cord 28 to again edect the grip of the head 16 on the guide, and the ends of the cords are then attached to the hook 31..

By so constructing the parts it will be seen that a simple and effective means is provided whereby the curtain and roller may be effectively held at any adjusted position within the frame, and may be quickly and easily released and moved to other positions as desired.

Having thus described inyinvention, what I claim as new therein, and desire to secure by Letters-Patent, is

1. In a curtain roller, the combination with a verticalguide strip of a clutch member comprising a shank portion revolubly supporting one end of saidroller and a head on the said shank having an aperture therein for receiving said guide strip, a spring mounted within the roller and attached to said shank to normally urge the shank head in binding relation with the guide strip, an arm extending laterally from said shank and insane for actuating said arm for the purpose set forth.

in a curtain roller, the combination with a vertical guide strip, of a clutch member comprising an apertured head portion for siidably receiving said strip and having an extended shank portion for revolubly mounting one end of said roller, a spring mounted within the roller and attached to the clutch shank to actuate the roller and to normally retain the clutch head in functional position, a curtain wound on the roller having a cross bar at its free end, a clutch member mounted at the-end of said bar having an ap ertured head slidable on and adapted to normally clutch said guide strip to prerent winding of the curtain on the roller, and means for individually releasing said roller and curtain clutches to efi'ect vertical adjustment of the curtain or roller.

3. T he combination with a window frame, of guide strips secured at opposite sides of the said frame, paired clutch members slidably mounted on said guide strips, a roller revolubly carried by the clutch members, a curtain wound on the roller, a spring mounted within the roller and attached to one of the mounting clutches for actuating the roller and for normally retaining the clutch in functional position, clutch members mounted at the free end of the curtain and slidable on the said guides for normally preventing winding of the curtain on the roller, pulleys mounted at the top of said frame, cables attached to said roller clutch members and extended over said pulleys to an acces ible point, whereby the said clutch members may be released from the guide strips and the roller moved vertically therealong.

4. The combination with ,vertical guide strips, of a curtain roller mounted between said strips, a curtain mounted on said roller, means for actuating the roller to wind the curtain thereon, a cross bar at'the free end of the curtain, clutch members comprising shank portions fixed in the ends of said cross bar having apertured heads slidable on said guide strips and adapted to bind thereon under tension of the curtain, and a trip cord attached to the said cross bar whereby the latter may be tilted to eflect a release of the clutch heads from the guide strip for the purpose set forth.

in testimony whereof I aiiir: my signature.
